  "details": "In the Linux kernel, the following vulnerability has been resolved:  ASoC: sma1307: fix double free of devm_kzalloc() memory  A previous change added NULL checks and cleanup for allocation failures in sma1307_setting_loaded().  However, the cleanup for mode_set entries is wrong. Those entries are allocated with devm_kzalloc(), so they are device-managed resources and must not be freed with kfree(). Manually freeing them in the error path can lead to a double free when devres later releases the same memory.  Drop the manual kfree() loop and let devres handle the cleanup.",
